ner as to permit a solution of increased strength to be used without injury vto the Specication of Letters Patent.

'roting ysolution to cut raw fur in such a manfiber of the fur, whereby the fur is treatedin a-maximumly effective manner, and matter which heretofore has been considered as waste may be advantageously utilized.

A further object of my improvement is'the A provision of a simple and'eiicient apparatus for carrying out my improved process.

Myinvention will be fully described here-f inafter and the features of novelty will be pointed out in the appended claims.

.Reference is to be had to the accompanying drawings which illustrate eXamples'of The apparatus as shown in Fig. 1 comprises a closed receptacle or chamber 5 in the bottom of which is located a carrier 6 preferably mounted on wheels 7 so as to be easily I Lmanipulated; a suitable opening, arranged to be closed by a door 8, being provided through which said carrier maybe moved:

into and out of the receptacle 5. In its upper wall the receptacle 5 is provided with a stack^9 which, at its upper end, communicatesf with the atmosphere and has its` lower' end located within the receptacle 5T and Vpreferably covered by a screen or simi- L lar-device l10. A blower* 11 has its inlet end connected with a source of supply of cut raw i fur or with aA hopper or the like 12 adapted `to contain such cut raw fur and has its exit endjconnected with a pipe 13 which extends through the upper wall ofthe receptacle-5 tand: terminates interiorly thereof near .the`

top, and lthrough whichthevcut raw fur may beblown into the receptacle 5. The carroting solution .14 is contained in a container `15, suitably supported, and connected with -thereceptacle 5 by'means of a tube 16 terminating in a nozzle 17 within the upper portion of said receptacle 5, an alr pipe 18 i therein. Abranch-19 may if desired extend from the pipe 18 into the solution'14 whereby air 1s forced into the same for the purpose of agltating said solution, and a pressure connected -with said pipe 18 to indicate the air pressure therein. In addition to this I prefer to provide the container 15 with a safety valve21 to permit any gases which may be formed beyond a predetermined .g pressure to escape therefrom.

In utilizing the apparatus so far described in carrying out my improved process the raw cut' fur passes from thehopper 12 or other source of supply to the blower 11 and is blown by the latter through the pipe 13 into the .upper portion of the receptacle 5 from which point. it distributes itself throughout the interior of said receptacle, traveling lengthwise thereof, and finally drops into the solution passes through the pipe 16 and under the, inliuence of the compressed air flowing from the tube 18 is sprayed through the nozzle 17 into said receptacle 5 into contact with the cut fur distributed therein by theblower 11. This cut fur in its passage to the carrier 6 in this manner subjected to chemically changed so that the animal grease is in this manner removed from the fiber of the fur. The screen 10 permits air and other gases to pass .out of the stack 9 while preventing the cut fur from escaping.I

During the operation of my improved apparatus the'solution 14 may be continuously agitated by the air passing through the branch 19 and thereby Amaintained' in a proper eectiveconditionat all times. With my improved process a much stronger carroting solution may be used than formerly and al1 portions of the cut fur receive va maximumly effective treatment, thus making it possible to advantageously lutilize material which heretofore has been regarded 'as waste having no special value.

In the forni of my apparatus shown in Fig. 2 the container 15EL for the solution 14 is located at a higher level than the receptacle 5 so that the pressuin of gravity is Patented Aug.' 11, 1914. Appuation mea March 17, 1914. serial No. 825,287.

carrier 6. At the same time the carroting the action of the carroting solution, that is,

indicator.20 of any desired type may also be added to the air pressure in reducing the said solution to a spray as it enters the said receptacle 5. Otherwise this'form of apparatus may be the same and operate the same as the form shown in Fig. 1. In -each case when the carrier 6 has become filled with treated out fur the door 8 may be opened to permit said carrier to be' removed from the receptacle 5' and emptied and then returned for anew supply, or a second empty'carrierV may immediately be introduced into said receptacley in order that an interruption of the process'may be avoided while the lirst car' rier is being relieved of its contents. It will, o fcourse, be understood that a A suitable means for introducing the solution 14 into the container 15 or l5a is provided, for instance in the shape of a pipe 22, Fig. 2 connected with asourceof such solution.

It will further be evident that other types of apparatus may be utilized to carry out my process and also that various changes in the specific forms shown and described and in the process described may be made within the scope of the claims without departing from the spirit pf my invention.

1. An' improvement in the art of carroting fur which consists in distributing cut raw `fur about in an inclosed space and prof viding a mist of carroting solution in said sp'acein the presence ofsaid fur.

2. An mprovementin the art ,of carroting'fur which-consists in blowing cut raw fur into a receptacle at the top and spraying a carroting solution into said receptacle into contact with the moving fur therein.

' 3. An improvement in the art of carroting vfur which consists in blowing cut raw fur into ,a receptacle at the top and spraying a carroting solution into said receptacle at 'the top vintol contact with the moving fur ,therein F t'. An improvement in the lart ,of carrotvingfun which consists in distributing cut fur about in a receptacle and causing vsaid distrlbuted cut raw fur to travel length- -wise of said receptacle and spraying a carroting solution into saidreceptacle into contact, with the moving fur.l therein. 5. An apparatus for carroting fur com* "prising a chamber adapted', tp confine a movingl distributed mass of cut raw fur and means for '.producing al mist of carroting solution in said chamber. l

6. An apparatus for carroting fur 4comprising a chamber, means for distributingl cut raw fur about in said chamber and causing said distributed cut raw fur to move lengthwise thereof and means for producing a mist of carroting solution in said chamber, in contact with said fur.

7 An apparatus for carroting fur comnprising a chamber, means for blowing cut raw fur into. said chamber and means for spraying a carroting solution into sald chamber into contact with the moving fur therein.

with the outlet of said blower and with the l interior of said chamber through which the cut rawf fur is blown into the latter, a container for a carroting solution, a tube corrnectin said container with the :interior of s'aid c amber and a pipe connectedwith a source oi compressed air. and extending into said chamber in proximity to said tube and forming therewith a meansfor reducing the carroting solution to al spray -in said chamber. I j

1'0. An apparatus for carroting fur com-v prising a chamber, a blower, a connection fromthe inlet of said blower to a source of supply of cut raw fur, a conduit connected with the outlet of said blower and with the interior of saidchamber through which the cut raw fur is blownv into the latter, a container for a carroting solution, a tube connecting said container with the interior of said chamber, a pipe connectedwith a source of compressed' air and extending into said chamber 1n proxnmty tosaid tube and forming therewith a means for reducing the carroting solution to a spray in' said chamber and a connection fromsaid pipe to said con-' tainer whereby compressed' air is introduced into the latter to agita'te the solution therein.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
